How Alaska escorts change prewar carrier risk

Pairing each carrier with an Alaska could make commanders more willing to deploy forward because the carrier is no longer exposed with only ordinary cruiser protection. That confidence partly rests on the belief that an Alaska has a credible chance against a Kongo, though the result depends on which rebuilt Japanese ship it meets. Two of the rebuilt Kongos are tentatively judged to have acquired enough subdivision to qualify as battleships. The same construction programme might bring some additional spending to Pearl Harbor, but the newest cruisers are expected to be at sea with the carriers when the attack comes. That leaves the carrier groups with a powerful escort even after the battle line is disabled. In the worst case, the large cruiser must interpose itself against a stronger enemy and buy the carrier time to escape or complete its mission. The fictional example of Gandalf holding the bridge in The Lord of the Rings illustrates that duty to protect the rest of the group at personal cost. The arrangement changes operational confidence without guaranteeing that any particular ship survives.
